Application July 21, 1953, Serial No. 369,300

Claims. (Cl. 1421) This invention relates to the class of machine toolsand more particularly to an apparatus adapted to enable the outersurfaces of comparatively large sized patterns to be properly faced.

The construction of this invention features means for mounting a cuttingtool on a portable and movable support whereby the cutting tool maytravel along a distance equivalent to the radius of the pattern beingfaced, the tool including guide wheels or discs adapted to engage thesurface of the pattern to be faced so as to enable the tool to beproperly adjusted for more eflicient cutting action.

Another important object of this invention resides in the provision ofmeans for moving the cutting tool inwardly toward the work piece or backtherefrom so as to enable the precise amount of cut to be predeterminedand pre-set.

Still further objects and features of this invention reside in theprovision of a portable pattern makers facer which reduces the amount oftime necessary in finishing the surfaces of patterns, which enables thepatterns to be surfaced with great accuracy, which is strong anddurable, and which is exceedingly compact while being very versatile.

These together with the various ancillary objects and features of theinvention which will become apparent as the following descriptionproceeds, are obtained by this portable pattern makers facer, apreferred embodiment of which has been illustrated in the accompanyingdrawings, by way of example only, wherein:

Figure l is a side elevational view showing the portable pattern makersfacer as utilized in surfacing a pattern formed from a compositeassembly of various pieces of wood or like material;

Figure 2 is a top plan view of the structure shown in Figure 1;

Figure 3 is a perspective view illustrating the construction of thecomponent parts of the invention in greatest detail;

Figure 4 is an enlarged vertical sectional view as taken along the planeof line 4-4 in Figure 2;

Figure 5 is a horizontal sectional view as taken along the plane of line5-5 in Figure 4; and

Figure 6 is a vertical sectional view as taken along the plane of 66 inFigure 4 illustrating the construction of the carriage and slide carriedthereby.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral 10 generally designates a lathe in conjunction withwhich the portable pattern makers facer 12 comprises the presentinvention is adapted to be used. The lathe 10 is conventional andincludes a drive shaft 14 provided with a face plate 16 upon which aWork piece 18 is suitably mounted. The work piece 18 is detachablysecured to a base 20 and constitutes suitable pieces or strips of woodor like material which are glued or otherwise secured together in anydesired relationship. In order to face provided, as is conventional.

the outer surface of the work piece 18 a cutting tool is However,cutting tools heretofore used were generally bulky, cumbersome, andincapable of being easily adjusted so as to assure maximum efficacy inthe surfacing of the work piece 13.

The portable pattern makers facer compirsing the present invention asindicated at 12 includes a vertical standard 22 formed from a tubularstructure which is mounted in a base 24 having casters or wheels 26provided therefor. The upper end of the tubular standard 22 is adaptedto receive a shaft 28 attached to a tool bed support 30. Threadedclamping means 32 of conventional design are adapted to clampingly holdthe shaft 26 relative to the standard 22. The tool bed support 30 isprovided with an internal recess 34 for reception of a dependingcylindrical end 36 of a tool bed. Clamping means 38 are provided foradjustably locking the cylindrical member 36 within the tool bed support30. The cylindrical member 36 is provided With a headed portion 40 whichhas an elongated bar 42 attached thereto to which bar there are weldedor otherwise secured end pieces 44 and 46. Extending through the endpieces 44 and 46 are guide rods 48 and 5%} which are preferablycylindrical in shape. Also journaled in the end pieces and 46 is athreaded carriage bar 52. A tool carriage 54 is positioned over the rods4% and 5t? and the carriage bar 52 and lockingly held in position bymeans of clamping plates 56 which are lockingly secured beneath theguide rods 43 and 51') and the carriage 54 by means of bolts 58.

The carriage 54 includes a lower member 60 which is provided with athreaded portion adapted to co-act with the carriage bar 52 so that uponrotation of the carriage bar 52 by means of handle 62. the carriage cantraverse from one side of the tool bed to the other. The

lower member 60 is provided with a dovetail slot 64 therein forreception of a slide 56 provided with a dovetail-shaped lower portion ofless size than the dovetail slot 64. A plate or strip 68 is receivedbetween the Walls of the lower member 6% defining the slot 64 and theslide 66 and is lockingly held in place by a set screw '70 to hold theslide 66 in adjusted position relative to the lower member 63. Bolted tothe slide as is a tool support plate 72 which carries a tool holder 74of conventional design for reception of a suitable conventional cuttingtool 76 or any other suitable tool used in finishing the outer surfaceof the pattern or wort: piece 18. A threaded adjusting rod 78 operatedby handle 89 is provided for moving the slide 66 and hence the tool 76inwardly toward the work piece 18 or away therefrom.

Three important elements of the invention are the guide blocks 82, 34and 86 which are slidably mounted on the guide rods 48 and 5t) and whichhave bifurcated end portions 83, 99, and 92 or reception of guide Wheelsor discs 94, 96 and 98 mounted on shafts 1 3i 192 and 1%. The discs orwheels 94, 96 and 3 are adapted to abut against the work piece 18.

it is to be noted that a scale or protractor ran may be provided on thelower portion or surface of the head 4%) of the tubular members 36whereby the tool bed may be adjusted relative to the tool bed support orcutting at an angle desired.

In operation, after the pattern has been placed on the face plate 16 ofthe lathe the portable machine is posi tioned in the tool bed support33. The guide wheels 96, 98 and 1% are positioned immediately adjacentthe rough pattern or work piece and the entire machine is square-drelative to the pattern. Then the pattern may be stalted revolving andusing the knurled handle 89, the cutting tool 76 may be positioned incontact with the wood of the work piece. After turning the handle 62 tocause the work piece to be cut for a suitable distance the lathe may bestopped and the portable pattern maker facer Patented May 15, 1956 12'may be re-s et so that the guide wheels or discs 94,

96'and 98 contact the finished portion of the work piece. The lathe maybe again started and the whole length of the machine can be traversedby. the carriage 54 to thereby inish the work piece. If it isnecessaryto take in a larger areathan that provided'by'the width of the bed ofthe machine, it i's only necessary to slide the base 24 I along with theguide Wheels 94, 96 and 98 against the finished work; The. guideWheelsf94, 96 and 98 will keep the entire assembly on a straight'path atall times.

Since from the foregoing the construction and advanljodimentrshown anddescribed, but all suitable modifications and equivalents may be readilyresorted to.
